GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 536,837, dated March26, 1895.

Application tiled November 3,1894. Serial No. 527,814. (Model.)

.To a/ZZ whom it may concern.-

Beit known that I, PHI-LIP M. GUNDLACH, a citizen of the United States,residing at Belleville, in the county of St. Clair and State ofIllinois, have invented certain new and useful Improvements inGrain-Drills.; and I do hereby'declare the following to be a full,clear, and exact description cf the same, reference being had to theaccompanying drawings, forming a part of this specification.

rI'his invention relates to that type of grain drills, and the feedingmechanism therefor, that forms the subject matter of my prior LettersPatent, No. 351,047, dated October 19, 1886; and the presentimprovements have for their objects, first, to provide a simple andeffective construction of the individual feed cylinder housings of agrain drill embodying the features of a simple and eflcient constructionof the inclined conveyer spout of such housing so that the fed grain'inits passage down through such spout will be y protected from the wind,and a spilling or wasting of such grain prevented; a`V simpleinterlocking sectional construction of such housing so that the partswill tittogether and interlock without the use of fastening bolts orrivets; and a cheap and durable means for securing the housing parts intheir interlocked condition, and which at the same time aords means forsupporting the rear end of the carrier chute of the drillflukes, in apivotal and slidable manner; second, to provide a strong and durableconstruction of the intermediate chute that connects the grain drillfiuke with the discharge spout of the feed mechanism, and withwhich thepassing grain is protected in a very perfect manner from the wind, andat the same time a very strong and substantial sliding and pivotalconnection is made between the rear end of such chute and the dischargespout of the feed mechanism; third, to provide a readily removable andreversible gage plate formed of spring metal that is adapted to changethe area of the outlet orifice of the feeding mechanism, and thus' gagethe amount ofgrain that is fed by the same; fourth, to provide a simpleand effective means for securing the cut o plates of the feedingmechanism at their required adjustment. I attain such .objects bytheconstruction and arrangements of parts illustrated in theaccompanying drawings, in which- Figure 1, is a longitudinal sectionalelevation, mainly on line -af, Fig. 2, of an individual feed mechanismand its connections; Fig. 2, a-plan view of the same; Fig. 3, atransverse section at line Fig. l; Fig. 4, a detail elevation of themechanism for securing the cut off plates of the feeding mechanism attheir required adjustment; Fig. 5, a view of the pointer portionthereof, detached; Fig. 6, an end elevation of the out off plate,detached; Fig. 7, a bottom view of the same; Fig. 8, an enlarged endelevation of the removable and reversible gage plate; Fig. 9, a sideelevation of the same; Fig. l0, an elevation of the hinged tongue orplate that has bearing against the fiuted periphery of the feed cylinderto retain the grain in the flutes of the same.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, l represents a portion of the bottom of thegrain box, on the under side of which are secured the series of grainfeed mechanisms by means of their housings 2, as usual. Each housing .2,will consist of two substantially counterpart members having ahorizontal plane surface that Iits against the bottom of the seed boxyand is provided with the usual opening for the down passage of the seedinto the feed mechanism proper, as in my former patented construction,and in the present improved construction each pendent side plate 3, willbe formed with an annular shouldered recess 4, to constitute abearing'for the plain cylindrical ends 5, of the longitudinally flutedfeed cylinder 6, so as to support the said cylinder in proper operativeposition. n

The feed cylinder 6, is of an annular cylindrical form, with its outersurface fluted longitudinally, so as to form grain feeding cavities, itsextreme ends 5, being left plain so a's to form bearings as above setforth. At its center it is provided with a spider 7, the hub of whichembraces the non-circular operating shaft 8, that is common to the wholeseries of feeding mechanisms, and is driven in the usual manner byconnections wit-h the driving wheels of the grain drill.

IOS

at its upper end in the pendent side plates 3,

tease? and adapted to bear against the lluted periphery of the feedcylinder to hold the grain in the tlutes of the same until the properpoint of discharge is reached.

10, is a rearwardly and downwardly projecting spout formed by inwardlydeflected portions of the pendent plates, and bya bot tom portion 11. Asthus formed the spout 10, will be of a narrowed natu re transversely,the purpose of which will be hereinafter more fully set forth.

12, are inturned lips on the side plates 3, partly cl-osing the topofthe spout 10, so as to shield the interior of such spout from thewind, and in connection with the narrowed nature of such spout asheretofore described, preventingin a very perfect manner any spilling orwastage of the grain.

13, is a hook on one side plate 3, beneath the spout portion thatengages over a lug portion 14, on the other side plate, so as to lockthe two plates together against an outward movement away from eachother.

15, are eyes at the extreme lower end of the spout portions of the sideplates 3, that are adapted to receive a cross pin 16, that is intendedto be driven into place, to prevent a movement of the one housing partpast the other in a circular direction.

NVith the above improved construction the two housing members areengaged with the bearing ends of the feeding cylinder, and with suchcylinder as a fulcrum the side plates are turned circularly until theirhook 13 and lug 14, are engaged to prevent lateral disengagement. lViththe hook and lng 13 and 14 in proper engagement, the eyes 15 on eachside plate will be in line to receive the pin 16, that locks the twohousing members to` gether against movement one past the other.

By the above improved construction the housing members are substantiallysecured together in a readily detachable manner Without the use ofscrews or rivets, and as so constructed admit of the ready casting ofthe parts without cores and requiring but little if any finishingprevious to assemblage together.

The cross pin 16, in addition to its function above described is adaptedto project at each side of the eyes 15, to formasupport for theintermediate chute 17, that conducts the grain from the spout 10, intothe bottom passage of the grain drill fluke. In the present inventionthis intermediate chute 17, is formed with reinforced inturned flangesor lips 18, along its top length, that rest upon the outer ends of thecross pin 16, to be supported thereby in a pivotal and slidable manner,so as to admit of the necessary movement of such chtite 17, in the usualmovements of the grain drill flukes. This chute is preferably made withstraight sides and an angular bottoni, as shown, as best adapted to itspresent particular uses. Other shapes may however be imparted to suchchute without departing from the spirit of my present invention.

19, is the horizontally sliding out olf, for regulating the quantity ofgrain fed by the feed cylinder 6, and which is guided in its movementbyguide lugs 20, on the end plates 3. This cut otT plate is divided intoa horizontal table portion 21, that in the adjustment of the cut offplate, changes the area of the opening, down through which the grainpasses to the feed cylinder, and an inclined hopper portion 22, that inthe aforesaid adjustment of the cut off plate covers more or less of thefluted feed cylinder and affords means in addition to the tableportion/2l, for regulating the quantity of grain fed by the tinted feedcylinder. In the present construction the table portion 2l, and thehopper portion 22, of the cut off 19, are connected together by aconnecting web 23. In the present construction the web 23, forms one ofthe walls of a grain containing hopper above the feed cylinder 6, andwhich has such cylinder as a bottom, and an end plate 3, the portion 22,and a vertical gage plate 24, as the other sides of such hopper.

The vertical gage plate 2l, in the present invention is formed of springor sheet metal, bent so as to form a flat main portion and a pair ofclips 25, that engage the horizontal portion 26, of the main housing 1,to effect an attachment. These spring clips are so positioned withrelation to the opposite edges of the gage plate, as to be nearer oneedge than the other, so that by a reversal of said plate, a greater orless opening will be formed between the feed cylinder and the adjacentedge of such gage plate.

The series of adjustable cut offs` used in the grain drill will beattached to the usual adjusting bars 27, common to all; and theadjustment of the same and the securing of the same at the requiredadjustment are effected by the following means:

28, is an index or pointer piece, secured to the bar 27, and providedwith a pointertinger 29, raised above the pair of lugs 30.

31, is an index plate secured to the grain box of the drill with itsfree end arranged between the pointer 29, and the lugs 30.

32, is awedge adapted to be driven between the pointer finger 29, andthe plate 31, to firmly clamp the parts together, and secure the slidingcut o of the feeding mechanisms at the required adjustment.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-
